This ultralight quad build is part 1 of the PROton build series. There will be a race PROton, 6" long range/freestyle PROton and this build, the ultralight PROton.
A lightweight quad with moderately powerful motors, this setup is great for beginner to intermediate pilots. A 1300mAh 4s will get around 5 min flight time.
** EDIT**
I made a boo boo. At 21:30 I soldered the Smart Audio to RX6 instead of TX6. It needs to go to TX6. Follow the schematic on the website. That's what happens when I film with a camera in my face.

If you found this post helpful, it would be super cool if you purchased the components from my store or purchase items from my Amazon links. These posts are expensive and take a loooong time to make so the purchases make it possible for me to keep making them. Thanks in advance, I greatly appreciate it :)
